Guess there is the same overlap of 5-10 questions.

Great Thanks Bunnel.

I know it will be too much to ask, could you bifurcate those gmat prep questions? I really want to keep them for later use, but at the same time I m very keen to use your PS and DS docs.

Sorry gurpreet, I don't know which particular questions are from Gmetperp, so can't do that.

I'm the author/creator of this doc. The questions are collected and compiled by me, also all solutions are mine.

Some of the questions were written by me, others come from open sources, so I don't think there is copyright violation.

sandeep800,

Bunnel has links to the discussions (which then say the source of the question). He's not giving himself credit for all of the content. He's linking to the discussions He's also not copying and pasting content into a document and putting his name on it.

The GMAC is fine if we discuss questions assuming everyone has access to the questions.

You took content from multiple sources, licensed and unlicensed and gave no citation of source, discussion, etc.

Sandeep,

This is not a comeback game. As mohater mentioned, Bunuel has clearly cited each and every source of information. I've mentioned this in another post of yours, maybe you didn't get around to seeing it. Questions from GMAT Prep or from the OG are okay as long as they are standalone and are meant for the purpose of collective discussion. It'd be like a group of friends getting together to solve problems. Compiling these questions, without citing sources and just putting them together in one document under your name and indirectly claiming credit for it is NOT acceptable.

I hope you understand what the difference between Bunuel's document and your document is. We want this community to be respectful of other people and their right to compensation for hard work. If you want to put together a document, feel free to write your own questions to illustrate certain problem areas or cite the link to the thread where the post has been discussed or write your own explanations. Copy-pasting from other sources is not the way to go. If you have any further clarifications, please feel free to PM one of us and we'll be glad to help you before you post another document.

Thanks.
